4The` Schedulev referred to in these Letters APatent and making part of the same.

To all 'whom it concern Be it known that I, .,WILLIAM WnnLs, ofAshtabula,

in the county of Ashtabula, andv State of Ohio, have in-r vented a new and useful Improvement in Hinges; and I do hereby declare that the following is a full, clear, and exact'description thereof, which will enable vothers skilled in the art to. make and use the same, reference being had to the accompanying drawings, forming palt of `this specification.

This invention relates to door-hinges; and l It consists in constructing Athe pintle, by which the two leaves of the spring are held together, with prol jections upon its bifurcated end, whereby shoulders areformed, to preventsaid pintle from being casually withdrawn, to disconnect the leaves, as will be hereinafter more fully described.

Figure 1 represents a plan view ofa hinge constructed according to my improvements', and

Figure 2 represents a section of the same, taken on the line a: a; of Iig. 1. Similar letters of `reference Aindicate corresponding pms. f

The spring A, is coiled around the pintle B, in the usual manner, and the'v ends 'O and DI hooked behind the leaves, to force them together,- the spring being appliedv under the necessary tension.

I continue the spring beyond the part O, whichvenl gages with the pintle, and bend it-back around the (preferably a button, with an eccentric edge,) which may be' turned into or out of the notches of thev spring .when the door is opened.

' The said pawl, engaging with thespring, will pre ing, it must be moved out of 'engagement with the spring.

This construction of the spring and pawl is substantially the same as shown in my patent of November 17,' 1868.

My 'present invention consists in the provision of a split springpintle, B, with enlargements, I, on the split lower end, projecting through the bottom of the hinge, and expanding, to prevent the withdrawal of th'e pintle, except when the parts are4 forced together, which may be readily done by the lingers, and the pintle withdrawn,- topermit the separation of the two leaves of the hinge, when required. v

I am aware that split pintles have heretofore been used; but the split ends were unprovided with enlarge:- ments, and could not therefore be applied to reversible hinges, where. it is sometimes necessary to introduce the pintle from the loweredge, with the split ends uppermost; The enlargements obviate this diiiiculty fully,

as they form a secure lock, and prevent the pintle frombeing casually displaced and lost.

Having thus described my invention, I claim as new, and desire -to secure by `Letters Patent- The split spring-pintle B, for hinges, when its' split end is provided with the enlargements or shoulders I, as herein described, for the purpose specified.A
